If Windows XP SP2 firewall service is set to manual or disabled when Windows XP SP3 is applied, the Windows Firewall/Internet Connection Sharing (ICS) service and Security Cetner service will be changed to automatic startup.  This behavior is by design, for the purpose of increasing the security of Windows XP.

This setting will remain in effect for computers that had the service startup manually altered.  
 
According to the Microsoft Enterprise Networking Team:
If the service is administratively disabled via domain Group Policy, it will again be disabled after subsequent application of Group Policy. The automatic service startup should only be seen on the first reboot after applying Service Pack 3. To cause GPO settings to be updated immediately on a client, run gpupdate /force from a command prompt.

Everytime I setup a Microsoft 2003 Small Business Server or troubleshoot connectivity problems to the SBS server I have to lookup the ports that are required to pass through a firewall for proper communication to occur with the various SBS components.  Since I’m tired of Googling for them, I’ve decided to post them here for my quick reference.  Hopefully others will find this helpful as well:

SBS firewall ports

SMTP - port 25 – email

http - port 80 – web server including wwwroot and server usage and performance reports

https – port 443 – secure web server.  Includes OWA and OMA

Windows SharePoint Services intranet site – port 444 for allowing users to securely access the intranet Web site created by SharePoint Services from the Internet

PPTP - port 1723 – VPN connections

Remote Web Workplace (RWW)  - ports 443 and 4125

Remote Desktop (RDP direct) – port 3389.  If using RDP through RWW this is not required.

Other SBS ports

POP3 – port 110

IMAP – port 143

IMAPs – port 993

FTP – port 21

Kiwi CatTools is a free (up to five devices) customizable utility that help network administrators automate configuration backups of their network devices such as routers and switches. It provides email notification and compare reports, highlighting configuration changes. Some of the features of CatTools includes:

  • Instant or scheduled device configuration backups where any differences can be instantly emailed to you.
  • Send CLI commands via Telnet or SSH to many devices at once.
  • Change device configuration at scheduled times.
  • Change all of your network device passwords at once.
  • Generate various device reports such as Port, MAC, ARP and Version.
  • Compare the startup and running configuration of devices.

All versions of CatTools have the same functionality. The extent of that functionality however is limited by the license you are running.

Check out the following screenshots of the product.  My only disappointment with the product was that there was no Sonicwall firewall preconfigured template.  Luckily, there’s detailed instructions on how to define your own devices and activities.  The premise is if your device supports Telnet, SSH1, SSH1.5 (Cisco), or SSH2 connectivity, you should be able to script automatic backups and perform other activities on it.


See the list of supported devices and an overview of the pre-configured activities.

Having problems getting applications to work through your firewall or router?  Use the online Port Forwarding Tester to determine if your device is properly configured to pass traffic through the appropriate ports.


This application will automatically detect the public IP address your browser is originating from, or you can specify the IP of your choice.  Next, enter the port number to test, and press the check button.  The web site will tell you if that port is opened or closed.


If you’re note sure how to open ports on your particular router, check out portforward.com. They have a detailed list of routers and firewalls with step by step directions on setting up port forwarding for different devices.


If you need more information on what port forwarding is and why you would want to enable it, start here or checkout the FAQ.  There is also a list of common ports that may need to be opened in order for your particular application to function properly.
